石腊切片对于研究植病是必要的技术,研究菌类的侵入寄主过程,也必须应用这种技术,方能了解病菌侵入的部位和侵入后发展情况。切片前把病菌孢子接种在寄主上,经过一定时间切下作石腊切片,可知道侵入丝侵入场所,侵入后的行动。每经过一个单位时间,作一次石腊切片,而且要作连续切片,可以看到侵入行动的整个过程。切片手续如下: Paraffin slices for the study of plant disease is a necessary technology to study the process of invasion of host fungi, but also must be applied to this technology, in order to understand the site of invasion of pathogens and post-invasion development. Inoculation of bacteria spores on the host before slicing, after a certain period of time cut off for paraffin section, you can see the invasion of silk invasion sites, after the invasion of action. Every pass a unit time, make a paraffin section, but also for a continuous slice, you can see the entire process of invasion. Slice procedures are as follows:
